Abstract
The present invention relates to a kind of coating film-forming methods, 1) coating film-forming methods are the following steps are included: be to apply a coating in substrate surface, this is one layer of cold coating film that can use ultraviolet light photopolymerization；2) ultraviolet light enables the film pre-hardening；3) with without photosensitive opaque printing ink, by required decorative pattern, add a printing layer in prevulcanized film coated surface；4) surface is formed by with ultraviolet light step 3；5) the pre-hardening layer below printing layer and printing layer is dissolved or is removed.Accordingly, the surface of substrate just forms the required resin coating film for having decorative pattern.The coating film-forming methods in substrate through the invention can form the required resin coating film for having decorative pattern in different substrate surfaces.
Description
Technical field
The present invention relates to technical field of coatings, are specifically related to a kind of coating film-forming methods.
Background technique
In recent years, people combine UV-curing technology with coating technology, successfully develop ultraviolet-curing paint,
Ultraviolet-curing paint has the advantages that high-efficient, consumption is low, and has the advantages that many traditional coatings are incomparable, is a kind of
Environmentally friendly coating can satisfy the different of people's life and require.
In recent years photocureable coating yield tells growth, and wherein photo-curing ink-jet and humour have developed rapidly, and China's photocuring produces
For industry since early 1990s realize large-scale production, photocuring product yield is always maintained at double-digit annual growth.
Currently, progress applies on the substrate surface for the purpose ofs to assign excellent appearance and performance etc. to substrate surface
Coatings composition simultaneously makes to be formed by wet coating and is solidified to form film.Consolidating for the wet coating is carried out by active energy beam
The active energy ray-curable coating material composition of change.From the viewpoint of energy conservation, productivity raising etc., crowd has been carried out to the latter
More research.
In various technical fields, with the coating surface film of substrate and the high adhesion of substrate.Single film coated surface is
It is not able to satisfy people to beautiful pursuit, how to form decorative pattern film in substrate surface is also problem to be solved instantly.
Summary of the invention
The purpose of the present invention is to provide a kind of coating film-forming methods, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme:
A kind of coating film-forming methods, which comprises the following steps:
It 1) is to apply a coating in substrate surface, this is one layer of cold coating film that can use ultraviolet light photopolymerization；
2) ultraviolet light enables the film pre-hardening；
3) with without photosensitive opaque printing ink, by required decorative pattern, add a printing in prevulcanized film coated surface
Layer；
4) surface is formed by with ultraviolet light step 3；
5) the pre-hardening layer below printing layer and printing layer is dissolved or is removed.Accordingly, needed for the surface of substrate is just formed
The resin coating film for having decorative pattern.
Preferably, the coating includes UV-cured resin, photoinitiator, diluting monomer and auxiliary agent.
Preferably, the substrate is one of plastics, metal plate, plank or cardboard.
Preferably, the UV-cured resin is epoxy acrylate, in urethane acrylate, polyester acrylate
One kind.
Preferably, the diluting monomer is one of isobutyl acrylate, TPGDA, HDDA, HEA.
Preferably, the photoinitiator is one of benzene methyl ethyl ketone or D-1173.
Preferably, the auxiliary agent is one of triethanolamine or acrylic amine.
Preferably, the ultraviolet light time of the step 1 and step 4 is 3~8 seconds, a length of 245nm of ultraviolet light wave~
303nm。。
Compared with prior art, the beneficial effects of the present invention are:
By the mutual cooperation of printing layer and film layer, in this way, not the surface coating of printing layer just will form into it is complete
The film of hardening, and the pre-hardening film under printing layer is not then fully hardened yet.At this moment, then below printing layer and printing layer
Pre-hardening layer is dissolved or is removed.Accordingly, the required resin coating film for having decorative pattern is just formed on the surface of substrate, this decorative pattern and print
Brush layer decorative pattern is in complementary relationship.
